1 Claim.

This invention relates generally to windshield attachments, and amongother objects, aims to provide an attachment which will prevent frostfrom forming on a windshield and obscuring the vision of the driver ofthe car. The invention provides a transparent frostv shield which may beattached directly to any4 glass or other smooth surface, and hence maybe used whenever and `wherever clear vision in frosty weather throughglass yor the like is essential.

In the accompanying drawing, showing a preferred embodiment of theinvention,-

Fig. 1 is'an elevation of the attachment shown mounted on a glasssurfacesuch as a windshield; 1 Fig. 2 is a section on line 2 2 of Fig.1;

Fig. 3 is a section on line 3-3 of Fig. 1; and

Fig. 4 is an enlarged section on line 4--4 of Fig. 1.

Referring particularly to the drawing, there is shown a frost shieldcomprising a frame 5, preferably rectangular, with one end 6 readilyremovv able so as to permit insertion and removal of a transparent sheetor pane 'l which is preferably of celluloid. From each end of the frame5 an arm 8 extends and a vacuum or suction cup 9 is attached to theextremity of each arm 8 to provide means for Vattaching the Vshieldsecurely to a smooth surface such as a window or Windshield I0, so as tolie in parallelism therewith and yet be readily removable at any time. agroove or channel on its ,underside and strips I l of rubber, felt orthe like are secured in said channel'and project outwardly to makecontact The frame 5 has y PATENT OFFIQE with the windshield or othersupporting surface, as shown in Fig. 2. Thus vibration of the frame iseliminated. 'Ihe transparent celluloid 1 has a multiplicity ofperforations l2, preferably round holes. 5

When the car is driven, the space between the transparent sheet 1 andthe Windshield is apparently filled with eddies or whirling air currentswhich move through the perforations l2 and in said space. Whether thisis a true explanation ofY the reason for the phenomenon, observationshows that frost does not form on the 'outside of the windshield so longas the windshield is pro tected by the device of the invention.

The device may be used on windshields of loco- 15 motives, motorboats,airplanes etc. as well as automobiles.

Obviously the invention may be embodied in various forms neither shownnor described.

Having described a preferred embodiment of 2O the invention, what Iclaim as new and desire to secure by Letters Patent is:

A device of the character described comprising in combination, a. frame;a sheet of transparent perforated material removably held in the frame;25 means attached to the frame to secure it in parallelism to anautomobile windshield or the like; and resilient means mounted on oneside of the frame and in Contact with'the windshield when the frame issecured thereto to seal the space 30 between thenframe and thewindshield.
